Ord currently holds a 30% interest in the Project and has elected
to sole fund an additional $1 million of expenditure before 10
February 2015 to earn an additional 15% interest. Ord can earn
up to a 75% interest in the Project. (Please refer to the
Agreements section and Table 6 below)
The updated DFS incorporated the recent K2 resource upgrade
announced 1st October 2014. The DFS assessed the economic
viability of underground mining methods to extract ore from K2
with toll treatment of ore at the nearby Northern Star Resources
(ASX: NST) owned Plutonic Processing Plant. Ord executed a
binding Ore Treatment Agreement on 24th September 2014 to
facilitate the processing of K2 ore.
ORD commissioned the study, by leading engineering and
services group, Entech Pty Ltd (“Entech”), with input from
various industry consultants.

Project History
The K2 deposit was last mined in 1997 by Resolute who had completed an underground
development Feasibility study in 1996. Resolute excavated a boxcut and established the
decline to access underground drill positions before the mine was prematurely closed
in 1998 after only minor amounts of ore extraction.

Mining:
The proposed underground mine will be accessed via the existing boxcut, portal and decline
development. This existing development will require some minor rehabilitation. It is proposed
that a mining contractor will be used to extract and deliver ore to Northern Star Resources’
Plutonic Processing Plant. Underground trucks will deliver ore to a specified location where a
surface haulage contractor will transport this material from the mine to the Plutonic plant.
The mine design includes rehabilitation of approximately 840m of the existing decline before
extending the decline and strike drive level arrangement. The decline is designed with a
minimum standoff of 30 metres from the main ore zone. Levels are designed at 20m level
spacing (floor to floor) implying that the stopes will be approximately 16m in height over a strike
length of 37.5m.
Figure 4: Planned Mine Development K2 Underground
The selected mining method of longitudinal open stoping with pillars has been determined to
be the optimal method for the style of mineralisation and geotechnical parameters. The mining
environment at K2 has been described as being relatively benign given the good rock mass
conditions and shallow depths.

Metallurgy & Processing:
Metallurgical test work completed concluded that K2 ore is amenable to conventional
processing methods and can be expected to yield metal recoveries in excess of 90%. A metal
recovery factor of 90% was adopted for the project, representing a value just below the lower
end of the range reported in metallurgical test work.
The Plutonic Processing Plant is located 36km from K2 via existing Haul Roads. The ore
processing schedule is based upon delivered ore being processed when made available to
Northern Star Resources’ Plutonic Processing Plant. Processing costs is all inclusive from the
point of delivery.
Site Infrastructure and Services:
Electrical power will be provided to site by a BOO (Build, Own, Operate) power station located
on the surface consisting of two 500kVa diesel generators producing power at 415V. The site
based infrastructure will be located adjacent to the box cut and includes a ROM pad, waste
dump, workshops, fuel storage and site based buildings, communications infrastructure and
explosives storage facility.

Mineral Resource Estimation:
The Mineral Resource estimates were compiled by Geonomics Australia Pty Ltd (“Geonomics”)
and are in accordance with JORC 2012 (Edition) Guidelines (ASX Release, Resource Upgrade at
Plutonic Dome Project 01/10/2014). K2 contains a total mineral resource of 415,000t at 7.7g/t
for 103,000oz Au at a 3g/t Au cut-off grade.

An Ore Reserve estimate was conducted based on the Mineral Resource estimation conducted
by Geonomics. The Ore Reserves have been estimated by Entech Pty Ltd and is similarly in
accordance with JORC 2012 (Edition) Guidelines. The Mineral Resources are reported inclusive
of Ore Reserves. The estimation was conducted based upon the information derived from the
Definitive Feasibility Study estimation conducted at K2. Cut off grades were determined based
on unit costs from the feasibility level mining cost model.
Ore Reserves were calculated by generating detailed mining shapes for each stoping block as
well as development. The designed stope shapes included planned dilution, being waste
material that was located within the mineable stope shape. A 10% unplanned mining dilution
factor was applied and is considered to be appropriate given the ground conditions and
proposed style of mining. 95% mining recovery was applied post geological interpretation to
6|Page
Ord River Resources Limited- www.ord.com.au – ASX:ORD
generate the final diluted and recovered Ore Reserve estimate. No Inferred Mineral Resources
were included in the Ore Reserve Estimation.
Infrastructure required for the proposed underground operation has been accounted for and
included in all work leading to the generation of the Ore Reserve Estimation. An 8% discount
rate was applied to the project and the NPV of the project is positive at the assumed
commodity price and exchange rate.
The financial parameters quoted are based on a Total Mining Inventory, generated during the
DFS. A detailed mine design and economic evaluation was used to generate the Ore Reserve
and Total Mining Inventory, which is completely sourced from underground mining.
The Total Mining Inventory contains some Inferred Mineral Resources. These are immediately
adjacent to, and/or below mined Ore Reserves. They have had the same modifying factors
applied as per the Probable Ore Reserve. Ord believes that it is reasonable to expect a
proportion of Inferred Resources to be upgraded when ore development and grade control
occur in these areas.
Ore Reserves and Total Mining Inventory are based on the K2 Mineral Resource reported on
the ASX by Ord -1st October 2014- “Resource Upgrade Plutonic Gold Project”. No material
change has occurred since reporting and Mineral Resources are inclusive of Ore Reserves.

Geotechnical:
Ground Control Engineering Pty Ltd (“GCE”) has conducted a feasibility geotechnical assessment
of the mine design and production strategy for the Ord Resources K2 project. The design and
production strategy was provided by Entech.
The geotechnical assessment completed by GCE is based on core logging data from seventeen
previously drilled geotechnical holes. The holes were originally drilled and logged by Resolute in
1995-1996. GCE completed a site visit in April 2014 to review and validate the historic
geotechnical logging, based on inspection of existing core from the drill holes available on site.
Additionally the K2 decline was inspected to determine the amount of rehabilitation required.

Sampling
techniques

Nature and quality of sampling (eg cut
channels, random chips, or specific specialised
industry standard measurement tools appropriate
to the minerals under investigation, such as down
hole gamma sondes, or handheld XRF
instruments, etc). These examples should not be
taken as limiting the broad meaning of sampling.
Samples were taken from Diamond Core and RC/RAB
chips, with drilling predominantly angled at -60⁰
towards 90⁰ (Local grid, 142⁰ MGA azimuth). Drill
spacing was on a nominal 15x10m grid for RC and
Diamond in the indicated portion of the resource to
40x40m spacing in the inferred material at depth. A
total of 1961 RAB, RC and Diamond holes are
included in the database for a total of 115,487m
drilling.
Diamond drill holes were surveyed via down hole
cameras at intervals of 30 to 50m during drilling using
an Eastman Single Shot Camera. A number of holes
were also surveyed by Sutron after drilling had
finished using either a gyro or DEMS tool.
 Include reference to measures taken to
ensure sample representivity and the appropriate
calibration of any measurement tools or systems
used.

Aspects of the determination of mineralisation
that are Material to the Public Report. In cases
where ‘industry standard’ work has been done this
would be relatively simple (eg ‘reverse circulation
drilling was used to obtain 1 m samples from
which 3 kg was pulverised to produce a 30 g
charge for fire assay’). In other cases more
explanation may be required, such as where there
is coarse gold that has inherent sampling
problems. Unusual commodities or mineralisation
types (eg submarine nodules) may warrant
disclosure of detailed information.
RC Holes were surveyed via a Single Shot Eastman
Camera at 30 to 50m. Deeper RC holes were surveyed
down the hole by Sutron on completion of drilling.
Diamond drilling was completed using truck mounted
rigs under contract by Northwest Drilling using mainly
NQ2 rods. Core was halved using a diamond core
saw, and collected generally at one metre intervals
for analysis, using geological/mineral boundaries as
main sample interval boundaries. Samples were
assayed for gold and arsenic at Amdel Laboratory
(Perth): gold analysis was conducted using a 50g
charge fire assay with AAS finish (detection limit of
0.01ppm Au)
RC Drilling was completed under contract by Drillcorp
using mainly Schramm rigs. RC holes were drilled
using a 5.5in face sampling bit and samples were
collected through a cyclone and riffle splitter both
mounted on a sample trailer, at one metre intervals.
Sampling of individual metres was done using a one
eighth riffle box splitter (the smaller split being
collected in calico bags for assaying). As with
diamond core, samples were assayed for old and
arsenic at Amdel using a 50g charge fire assay with
AAS finish. Pre-collar material was collected using
PVC bags at one metre intervals, and four metre
composite scoop sampling was then undertaken
RAB drilling was conducted under contract by
Connector Drilling, with material laid out on the
ground in one metre intervals and four metre
composite spear samples subsequently collected for
assaying. Bottom of hole samples were taken on a 2m
interval. All composite samples were assayed for low
level gold to 1ppb detection limit at Genalysis
Laboratories in Perth using a B/ETA technique (50
digest, solvent extraction, graphite furnace AAS
finish). Samples that returned greater than 0.1g/t Au
were re-sampled on one metre intervals at a later
date and submitted for low level gold analysis.

A surveyed Digital Terrain model was provided by
Dampier Gold (Project JV partner) to ORD which was
used to define the current working surface.
Drill spacing was on a nominal 15x10m grid for RC and
Diamond in the indicated portion of the resource to

A summary of all information
material to the understanding of the

tabulation of the following information
for all Material drill holes:
The K2 deposit is located close to the middle of
the Plutonic Well Greenstone Belt, which forms
part of the Marymia Inlier. The Marymia Inlier is
a granite-greenstone terrane situated between
the Yilgarn and Pilbara Cratons in Western
Australia. The Plutonic Well Greenstone Belt is
a north-easterly trending belt approximately
50km long and 10km wide. It consists of
predominantly mid to upper greenschist facies
metamorphosed ultramafic volcanics, tholeiitic
basalts, minor felsic volcanics and sediments.
The local Geology of K2 is composed of a series
of North-East, South-West trending mafics,
ultramafics and metasedimentary lithologies
metamorphosed to lower amphibolite facies.
Gold Mineralisation within the K2 pit showed a
strong association with lithological contacts and
high grade zones at the contact between a highFe and high-Mg amphibolite unit.
The drill holes reported in this announcement
have the following parameters applied. All drill
holes completed, including holes with no
significant gold intercepts are reported in this

understanding of the report, the
Competent Person should clearly
explain why this is the case.
All results relating to the drill sections provided

·
In reporting Exploration Results,
weighting averaging techniques,
maximum and/or minimum grade
truncations (eg cutting of high grades)
and cut-off grades are usually Material

been top cut to 50g/t Au. Lower cut off is
nominally 0.5g/t Au with a minimum modelled
width of 2m downhole.

Where aggregate intercepts
incorporate short lengths of high grade
results and longer lengths of low grade
results, the procedure used for such
aggregation should be stated and
some typical examples of such
aggregations should be shown in

Sample lengths from RC/RAB drilling are all 1m
lengths. As diamond core is cut to geological
boundaries and incorporates shorter intervals,
length weighted averaging has been used to
make 1m downhole composites.

The interpretation of the deposit was carried out
using a systematic approach and was of
consistent orientations and dimensions as
previous resource model used in the mining of,
and observable in, the K2 pit. Given the close
spacing of drill holes confidence in the
geological interpretation is considered high
·
Nature of the data used and of any
assumptions made.
The use of historical drilling provides a level of
uncertainty as the validation and QA/QC of
historic data is not always possible. Where
instruments susceptible to magnetism have
been used in downhole surveys azimuths have
been assigned to the survey data. Generally
this has only been applied to shallow holes
drilled from surface, with valid azimuth and dip
data available for the deeper holes used in the
resource calculation
·
The effect, if any, of alternative
interpretations on Mineral Resource estimation.
The previous resource model for K2 was
constrained around high grade zones and not
modelled to follow the controlling structure. This
has resulted in significant increase in total
tonnes and ounces
Inconsistencies in the logging of historic drill
holes made detailed geological interpretation
difficult. However the company believes this is
mitigated by the current model matching the

The Ore Reserve estimate is based on the Mineral
Resource estimate carried by Geonomics Australia Pty
Ltd.
The Mineral Resources are reported inclusive of Ore
Reserves.
A site visit has been conducted by the Competent Person.
The visit included inspection of potential surface
infrastructure positions as well as pre-existing decline

Feasibility level studies have been completed for all areas
of the K2 Underground Project. Ore Reserve estimates
are based around the assumptions completed for the K2
Project Feasibility Study.
Cut-off grades were determined based on unit costs from
the “Feasibility Level” mining cost model
The Ore Reserve estimate has been calculated by
generating detailed mining shapes for each stoping block
as well as development. Designed stope shapes include
planned dilution, being waste material that is located
within the minable stope shape. Additional unplanned
dilution is also generally incurred from the walls of stopes
due to re-distribution of stress within the rock mass as
voids are created in the mine, blast damage, poor mining

assessment of the mineralised zone is also favourable for
the selected mining method.
A 10 % unplanned dilution factor has been calculated by
Entech. Entech considers this to be appropriate given the
ground conditions and proposed style of mining
A mining recovery factor of 95% has been applied post
geological interrogation to generate the final diluted and
recovered Ore Reserve estimate. This mining recovery is
applied to allow for any ore loss due to mining related
issues such as; underbreak due to poor drilling and
blasting techniques, stope bridging or freezing or
material being left in stopes due inaccessibility.

Many local and international operations are operating at
C3 cash costs above current prices or hedges. Supply
likely curtailed if current pricing and revenues structures
maintained. Active international Reserve Bank, hedge

The Ore Reserve estimate is based on a financial model
for that has been prepared at a “feasibility study” level of
accuracy economic modelling.
All inputs from
underground operations, processing, transportation and
sustaining capital as well as contingencies have been
scheduled and evaluated to generate a full life of mine
cost model. Economic inputs have been sourced from
suppliers or generated from database information
relating to the relevant area of discipline. A discount rate
of 8% has been applied. The NPV of the project is positive

Plutonic Dome Gold Project. Currently Ord River
Resources holds a 30% equity interest in the Project.


The statement should specify
whether it relates to global or local
estimates, and, if local, state the
relevant tonnages, which should be
relevant to technical and economic
evaluation. Documentation should
include assumptions made and the
procedures used.
The Ore Reserve has been peer reviewed internally and is

The design, schedule and financial model on which the
Ore Reserve is based has been completed to a “feasibility
